Ahhh....
This is true.

I copy the wrong version of the example.
But I have understand the matter.
When I make a widget composed by others widgets I need to ovverride OnSize
event whit a function like this.

...
EVT_SIZE(Display::OnSize)
...

void Display::OnSize(wxSizeEvent& evet)
{
 Layout();
}


This is written in the docs... :-)
I didn't read carefully. :-(

Thanks for your answer.
